tty: moxa: Locking clean up
- The open lock is needed to fix up the case of a board reset occuring during
tty open but too early for a sane hangup response.
- The lock can however got for other cases
- Use the port mutex for get/setserial
- Fix up the confused lack of locking on the THROTTLE and other bits in the
private flags. Just use set/test/clear bit and it covers the cases we need
